The most well-known site of the DMZ and the closest point to North Korea, is the JSA (Joint Security Area, pictured). Here soldiers from both countries face each other with only a few feet of gravel in between, always ready to act in case of an emergency. In the JSA, negotiations between North and South Korea are held, with no negotiator having to leave their country, because the border runs right through the centre of the building and even the table the delegates sit around.
